Abstract: Vertical shaft for shield launching is an important structure for construction. The construction condition impacts a lot on the designing which directly controls the construction scheme. The desiging of assistant vertical shaft for shield launching and passway is discussed, the structure types of vertical shaft and modes of main tunnel into passway are comparatively selected according to the requirements. The rational designing plan is proposed. In the end, safe construction is guaranteed.
